maybe I was wrong, after some browsing I found out the park seems to be new, the offices are gone and that indeed the location of the SAP office was off - I updated it to the correct building

this park seems to be gone actually, and there are multiple offices here, all with the same address - I created a note on this park with the comment that there are now offices here

thank you! sorry, I'm new to OSM, a lot to learn :)
I did not add "building=yes" manually, no idea what happened there - and the addresses were showing empty to me, which is why I added them - will take those into consideration next time
